What will he change about her

A new toy could be fun

His mother had been nagging to him about various things these past few months. Being constantly lectured was pretty draining for him. After thinking about what he could possibly change about his mother, he settles on the perfect idea.

Rather than dealing with an overbearing mother, he decides she'd be better off as his personal relief aid-
A sexdoll.

He snaps his fingers and changes his mother into the perfect lovedoll.

Her lips fill up to look perfect for sucking, her mouth opens agape into a perfect O soon after.
Her breasts and buttocks expand quickly, reaching the size of large melons.
Her arms take on an L shape in the style of classic dolls, while her legs perfectly straighten into a V position.
Her skin turns into nothing but shiny rubber, seams run down her limbs and across her body.
Her mind is still there, he want's her to know what's going on- but she won't be able to do anything about it. Objects can't move on their own after all.

He believes he's done for a moment, but remembers to top off the sexdoll look with a valve where her belly button should be.

With some extra last adjustments to give it more of a personal touch, his mother now resembles a high quality blow up doll anime-esc version of her self.

After appreciating his own amazing work of his new toy, he takes a breather to consider what else he could do. Test out the mom doll? Maybe make some other members of his family into things?
